gizmo_the_mogwai [7]

Answer:

25002m

Explanation:

V = 100 km/h

Converting to m/s, we have

V = (100 x 1000)/3600 = 27.78m/s

t = 15mins = 15 x 60 = 900secs

Displacement =?

Velocity = Displacement /Time

Displacement = Velocity x time

Displacement = 27.78 x 900

Displacement = 25002m

Since displacement and distance are measured in same unit, the distance between A and B is 25002m
